Cobalt Blue Glass Rod

A001


2 in stock

Of the four shades of cobalt blue Northstar produces, this ranks as the second lightest. Cobalt Blue is well suited for small blown work, as well as sculpture when a medium transparent blue is desired. Cobalt Blue can take a lot of heat and can be worked in a wide range of flame settings. Though the color is extremely intense, be sure to stay out of reducing flames to prevent any dulling or graying. Available in 1/4 lb increments.
